This software is intended to run on the moodlamp by muccc. (http://wiki.muc.ccc.de/moodlamp) Currenty (and for the foreseeable future) it is very concerning features. However, it will hopefully have a better documented protocol and run more stable. A more precise protocol description will follow at some point, also, the protocol will probably change until there is a real spec. Commands are line based and end with \r or \n or both. The only real command is 'iRRGGBB' - it sets the LED to the given color immediately, where RR, GG and BB are hex numbers between 00 and ff. Also, there is q. This turns on verbose mode. Right now, this means, the moodlamp will echo what is entered and acknowledge commands. In a future version, verbose mode will probably be default and applications should take care to turn it off if they generate bulk traffic. I know this could be much better, but I am not in the mood to think about the right solution for this here and now. If a command was not unerstood, a single question mark is printed.
